Our GY-302 module is equipped with the BH1750 light sensor. It has a very large measuring range and, thanks to free libraries, finally outputs brightness values in lux. The module is connected via the I2C interface, therefore only 4 cables are needed.Thanks to the integrated level converter, the module can be supplied with both 3V and 5V and is compatible with most microcontrollers. https://elecena.pl/product/17485408/gy-302-bh1750-light-sensor 2021-03-29 https://elecena.pl/product/17485408/gy-302-bh1750-light-sensor 2023-08-14
